CONNECTING LINK FOR DRIVE CHAINS.
Application'led April 19, 1923. Serial No. 633,253.
To all whom it may concer/n.'
Be it known that I, JOHN C. CHAPMAN,
a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Connecting Links for Drive Chains, of which the following is a specification.
My invention relates to drive chains and particularly to connecting` links for e such chains. My invention will be better understood by referring to the followingdescription taken in connection with the accompanying drawings forming a partthereof and in which Figure 1 is a plan view of a portion of a chain to which my invention may be applied; Figure 2 is a side View of the chain shown in Fig. 1; Figure 3 is a sectional view on line 3 3 of Fig. 2; Fig- 20 ure 4 is a side elevation of a connecting link embodying my invention with the bushing shown in section; Figure 5 is a perspective view of the bushing and Figure 6 is a perspective view of the pin upon which the bushing as shown in Figure 5 is placed.
My invention relates to connecting links for drive chains of various types where bushings and rivets are used in the joint construction. Chains of this character are shown in Patent No. 959,047 granted May 24, 1910, and Patent No. 1,020,180 granted March 12, 1912, to W. J. Belcher.
In the drawings I have. shown for illustrative purposes the type of chain shown in the latter of the above patents. The chain shown is made up of units 1, through'the ends of which extend bushings 2 and through which bushings extend pins or rivets 3. The pins 3 are connected at their ends by side plates 4, the ends of the pins 3 being riveted as shown. In making up chains it is necessary that they be of different lengths` and-it is also necessary that the ends of the chains be left free so that the chains may be placed upon the driving and driven. gears or sprockets and the ends fastened together after the cha-ins are so applied. This necessitates the use of connecting links for securely fastening the ends of the chains together. In the assembled portions of the chains the bushings 2 are placed through the openings in the ends of the chain units and are then fastened in the outer chain units. On account of the intermeshing of the chain units at the ends of the chains the bushings are not fastened in position in these openings at the time of shipment, but the bushings are supplied separately and assembled on the field. Heretofore, connecting vlinks have been supplied wherein the ings, wherein the connecting link comprises two pins 5 and 6, one end of each of which is riveted in a side plate 7. The pin 6 is provided with a circumferential groove 8 intermediate its ends and the bushing 9, as shown in Fig. 5, is provided with a cylindrical opening 10 therethrough and one side of the bushing is flattened as shown ati-11. The bushing is also provided with two openings 12 for lubricating purposes. In preparing the connecting link, a bushing 9 is slipped on the pin 6 and by means of a suitable tool the wall of the bushing is depressed into the groove as shown at 13, in Figure 4, so that the bushing is prevented from slipping oi of the pin. The portion 13, however, is not pressed downward sufficient to so contact with the reduced portion of the pin 6, as to interfere with the free rotative movement between the pin and the bushing. In the illustrative drawings I have shown the indentation 13 in the thinned part of the bushing wall, but this indentation may be made in any part of the bushing wall adjacent the groove 8. When the chain is to be assembled, the ends are brought to the position shown in Fig. 3 and the connecting link is inserted so that the pin 5 passes through the bushing 2 and the bushing 9 passes through the openings in the chain units 1. The openings in the units 1 are so shaped that the bushing fits therein and is held against rotation by reason of the fiat portion thereon. A side plate similar to the side plate 7 is then placed on the ends of the pins 5 and 6, and these ends are riveted so that the plate is held in position.
From the foregoing, it will be evident that by the'simple'expedient shown in detail in Figure Il; a suitable connecting link provided and provision is made, whereby the bushing is fixed on its pin, Without, in anyl manner, interfering with the desired operation of the bushing on the pin. By reason of this arrangement the ends o the pins 5 and 6 are stronger thanir` al1-opening were made through them as has been done heretofore and the manufacturing oost or the connecting links is substantially reduced,
whileat the fsametime there is nofpossihility ofth'e'bushings becoming detached from the pins and becoming lost. This arrangementsaves considerable time andvtrouble in the assembly of the chain. Many other advair tages will be apparent to those skilled in the art.
While my connecting link is particularly useful in chains of the typesr above men'- tioned it will be evident that it may also be used in other types of chains and in some instances, special connecting units are provided :tor chains of the above types and l desire it to be understood that my connecting links may be used in connection with such special means.
